摘要： A process for printing an image on a substrate comprising applying to the substrate by means of an ink jet printer an ink comprising the components: i) an encapsulated pigment comprising a pigment core and a cross-linked dispersant shell; ii) a binder having a weight averaged molecular weight of at least 5,000 which is or comprises a polyurethane; and iii) a liquid vehicle; wherein the binder is chemically different from the dispersant in the shell. The process provides prints having good highlighter smear resistance. The inks print well and are especially stable.

摘要： A process for preparing a dispersion of a particulate solid comprising: dispersing a particulate solid with a dispersant and a liquid medium, wherein the dispersant is a random copolymer obtained or obtainable from the copolymerisation of a composition comprising: i)optionally one or more monoethylenically unsaturated hydrophilic monomers, ii)one or more monoethylenically unsaturated hydrophobic monomers, iii)one or more di- and/or higher- ethylenically unsaturated monomers, and iv)one or more chain transfer agents wherein at least one of the chain transfer agents has one or more hydrophilic groups; wherein the dispersion step is effected by a mechanical treatment which reduces the particle size of the particulate solid; and with the proviso that when: A)the dispersant copolymerisation composition comprises one or more monoethylenically unsaturated hydrophilic monomers as component i); and B)any of the chain transfer agent(s) in component iv) is 3-mercaptopropionic acid, acrolein or methacrolein; then in that case the ratio of the total hydrophilic groups in all of the one or more monoethylenically unsaturated hydrophilic monomers of component i) expressed in moles to the total amount of hydrophilic groups in all the chain transfer agents of component iv) expressed in moles is less than 5:1.

摘要： A process for preparing a dispersion comprising the stages: i) providing a dispersion comprising a particulate solid, a liquid medium and a dispersant having cross-linkable groups and a weight averaged molecular weight of from 1,000 to 70,000; and ii) cross-linking the dispersant in the presence of the particulate solid and the liquid medium thereby preparing a dispersion of an encapsulated particulate solid, wherein the cross-linking is performed such that 0.01 to 0.5 mmoles of cross-linkable groups in the dispersant are cross-linked per g of dispersant; said process also comprising at any stage: iii) adding a metal chelating agent to the dispersion; and after stage iii) the stage of: iv) removing at least some of the metal chelating agent from the dispersion.
